What is ISO certified testing?

When accrediting a laboratory, the external assessors use known standards and procedures to determine the technical competence of the laboratory. By following these standards, such as ISO 17025 standards, it is possible to conduct an evaluation of the factors that are critical in the production of the test. These elements cover a wide range of aspects as can be seen from the list below.

• Experience, qualifications and technical ability of key staff.
• Maintenance of testing equipment to the required standards.
• The environment in which the testing is carried out.
• The way the samples are handled, recorded and moved around the lab including trace-ability.
• Quality assurance of the testing and the calibration of the equipment.
• Ability to identify problems and solve them effectively.

What is accredited testing?

All the above ensure that a laboratory operates to the required standards and is capable of producing reliable and accurate testing on a continuous basis.  Being AABB accredited also is a means of differentiating between normal DNA testing and the higher quality of an accredited DNA testing laboratory.  AABB certification is a yearly inspection that ensures the lab goes above and beyond ISO certifications and is capable of performing DNA tests beyond the specifications for government and legal testing. 

You can rest assured that all tests processed by Paternity Testing Lab USA are performed by a laboratory that is both state-of-the-art, highly certified, and AABB accredited. Having a laboratory that is inspected and accredited to do DNA tests performed at the highest industry standards has always been a priority at our company.

The accuracy of our DNA tests

At PTL all our all our paternal and maternal testing is performed on 23 genetic markers (the 23st genetic marker is used to confirm the sex of the person) to ensure that the results are highly accurate. On this basis, in the case of our paternity tests, if the alleged father is the actual biological father of the child, then all 23 genetic markers will match those of the child. We normally refer to this as “no exclusions”. We can also guarantee that in cases where the test is conducted utilizing the alleged father, mother and child – the result will yield a probability of paternity of more than 99.9999% where the father is included and a 100% exclusion rate where he is not the father.

In situations where the paternity test is performed using a single parent, the resulting probability is in most cases greater than 99.99%, although an exact minimum probability of parenthood as per above cannot be determined in advance.

As a result of such extremely high probabilities, you can rest assured that the result of the DNA test is accurate and will provide conclusive proof of the existence of a biological relationship or otherwise.

For your information, we have also provided sample paternity test results ; here you are be able to view what a paternity test result looks like. The page also contains comprehensive information about how you go about understanding your results.
